Introduction to Black PE Sheets
Black PE sheets are panels primarily made from polyethylene (PE) with the addition of carbon black pigments and UV inhibitors, produced through extrusion or calendering processes. Depending on density, they are mainly classified into High-Density Polyethylene (HDPE) sheets and Low-Density Polyethylene (LDPE) sheets.
Core Characteristics
| Characteristic | Description | Advantages |
| Excellent Chemical Resistance | Highly resistant to chemicals such as acids, alkalis, and salts. | Suitable for corrosive environments like chemical containers and electroplating tanks. |
| Good Impact Resistance | Particularly HDPE sheets offer high impact strength. | Ideal for manufacturing parts requiring impact resistance, such as storage boxes and transport containers. |
| Low Friction Coefficient | Smooth surface with low friction coefficient. | Suitable for slides, liners, and other low-friction components. |
| Strong Weather Resistance | Enhanced with carbon black and UV inhibitors, offering excellent anti-aging properties. | Suitable for outdoor use with a service life of 5-10 years. |
| Non-Toxic and Odorless | Complies with food safety standards. | Applicable in food processing and packaging industries |

Processing and Usage Recommendations
1. Processing Methods:
· Machinable (sawing, drilling, turning, milling).
· Thermoformable.
· Weldable (hot air welding, extrusion welding).
2. Usage Recommendations:
· Avoid prolonged exposure to high temperatures.
· Avoid contact with strong oxidizing agents.
· Allow for appropriate expansion gaps during installation.
3. Cleaning and Maintenance:
· Clean with mild detergents.
· Avoid strong acid or alkaline cleaners.
· Regularly inspect surface wear.
Black PE sheets are cost-effective, versatile engineering plastic panels with excellent chemical resistance, impact resistance, and weather resistance. Although they have limitations in temperature resistance and stiffness, selecting the appropriate type (HDPE or LDPE) and specifications can meet most industrial application needs. Their black appearance is not only aesthetically pleasing but also provides superior UV resistance, making them ideal for outdoor applications.
